properly the large service area which they present. They further involve the very considerable disadvantage that they have no means to confine the urine spatterings to the flushed area, in consequence of which such spatterings wet the shoes and trousers of the user and soon produce an unclean and unsanitary condition in and around the urinal. They are, moreover,- extremely difficult to form because their size and the fact that they contain no inherent reinforcement make them awkward to handle without distortion before they be come hardened in thekiln and give rise to warping in the baking process.

This invention consists in certain improvements in urinals of the kind indicated having for their objects to produce a urinal of this type which shall more perfectly fulfil the requirements of sanitation and cleanliness than those now inuse, may-be manufactured with less possibility of dis- Inore efiicient and suitable for the special purpose for which such structures are in "tended. V k

In the accompanying drawings, in which] the invention is fully illustrated, Figure 1 is a perspective view of the improved urinal; Fig. 2 is a substantially central vertical sectional view thereof; Fig. 3 is a plan viewyand, Figs. 4 and 5 are horizontal sec tional views on line 00-00 and 'yy of Fig. 2.

The stall formation of the improved urinal is obtained in the preferred form of-the invention illustrated by employingtwo vertical walls a a set at an angle'preferably 90to each other. These walls are joined at the bottom by thehorizontal wall 6, and

its top surface at the'top by the ledge or overhang 0. They are further joined by the wall (Z which forms "at the back in" such manner that the/drip from the inner surface of the urinal chainberwill'fall directly into it, as will hereinafter he more'particularly explained. The wall b' isadapted to be set in the floor of the apartment, as shown in Fig. 2, so that it will beiflush with the floor surface; I y

Theledge or'overhang a has its upper surface ihorizontal, but its under surface j isv beveled, the angle of the bevel increasing from each outer end of the ledge toward the middle thereof, the result being to improve the appearance of the whole structure, reinforce its upper part (especially against, distortion either before or. while undergoing the baking process) and give the necessary pitch to the bottom of a watersupply chamberlc, which is formed in the said ledge, toward the discharge outlet Z of said chamber; the outlet Z may be a series of holes or other means for discharging the water from the chamber 72 downwardly into the urinal chamber and in all directions against the walls of the latter. m is any suitable means for introducing water into the chamber .70.-

" The wall (Z bulges outwardly at the bottom," as indicated at a, the width ofthe thus-formed forwardly projecting part of the urinal-chamber-forming portion of the structure being such that a person usmg the urinalmay standnwith said part more or less under himand his feet both sides of it. From its lower end upwardly said wall, viewed in front elevation, tapers gradually, as shown in Fig. 1. The maj or part of the urinal chamber from its intake (outletl for the water supply chamber is) downwardly graduallytapers upwardly, this being because both walls a a arevertical and the Patented Oct. 20, 1914.

major upper part of wall 0? slopes rear-- the urinal chamber downwardly to an extent including especially, and at least, thev part of said chamber which is subjected to direct urinal service; in short, the formation of the urinal chamber is such as to encourage a surface-flow rather than a drip' or free falling of the flushing water and a surface-flow that is uniformly distributed over the whole interior face of the urinal chamber and especially that part thereof which is most frequently and directly wetted by urine. This advantage is accomplished, it will be observed, by use of a localized or single intake.

Wall is formed with a vertically elongated opening 0 extending from a point near the top of the wall cl well to the front of the bulging portion a of said wall, but sufficiently above the bottom wall 6 to leave the lower front part of wall (Z intact excepting (in the preferred form) for a vertical slit 3) which extends from said wall Z) upwardly, merging into the opening 0. Below the opening, therefore, the wall cl serves as a guard or fender to prevent drippings of urine from spattering from the wall 7) outside of the urinal chamber; the disposition of the lower end of said opening is such that it is well under the user, so that such drippings fall within the chamber and not on exterior surfaces. It will be observed that'the angular disposition of the walls a a makes the interior back surface of the urinal chamber concave, as at a, and that the aperture 0 is relatively narrow with respect to the inside width of the urinal chamber, thus the spattering action of the urine against the back wall of the structure is minimized and in any event is confined wholly within the urinal chamber. The slit 2? is useful to permit drainings from the floor, when the same is mopped or washed, to find their way into the urinal. To confine the flushing water within the urinal chamber wall (Z may be provided with an interior flange 1 extending substantially all around the "opening 0 at the edge thereof.

The flushing water enters the outlet 9 more or less from all sides thereof, and if desired an auxiliary stream of clean water may be supplied from the chamber is to the said outletvby the duct 3 formed in the back of the urinal structure. I find it desirable, however, as more effectively flushing the outlet to have the back surface-portion 1" of the chamber 6, which surface-portion stands vertically directly over the outlet, so that there will be a drain of water directly into said outlet as well as the surface-flow thereinto.

In the back of the urinal structure may be formed a vertical duct 25 for carrying off odors and gases arising from the outlet, the same reaching from basin f upwardly to any suitable pipe leading out of doors.

It will be understood that the walls a a are disposed in angular relation to each other so as to afford wings imparting privacy to the urinal proper. Regardless, however, of the relation and function of the walls it will be apparent that the entire structure is materially strengthened by the existence therein, as a brace between said walls, of the wall cl forming a urinal chamber therein, so that the structure is capable of being handled, before it reaches the kiln, with less likelihood of becoming distorted and of undergoing the baking process with less susceptibility to warping influences.

I do not wish to be limited to the precise construction herein shown and described, what I claim being,

1. A urinal having a urinal chamber provided with a front wall and a bottom, said wall having a vertically elongated opening of limited width relatively to the inside width of the urinal chamber and extending downwardly in said wall short of said bottom and also having a narrow vertical slit extending from said opening downwardly to said bottom.

2. A urinal formed of ceramic material and consisting of two upright walls joined with each other and arranged angularly and a vertically elongated apertured front wall arranged in the angle between and joined from top to bottom at its lateral portions with said first-named walls and forming with the parts of the latter relatively back of it the urinal chamber, the remaining parts of said first-named walls forming forwardly projecting wings.

3. A urinal formed of ceramic material and consisting of two upright walls joined with each other and arranged angularly and a vertically elongated apertured front wall having an upwardly tapering form in front elevation and arranged in the angle between and joined from top to bottom at its lateral portions with said first-named walls and forming with the parts of the latter relatively back of it the'urinal chamber, the remaining parts of said first-named walls forming projecting wings.

4. A urinal formed of ceramic material and consisting of two upright walls joined with each other and arranged angularly, a vertically elongated apertured front wall arranged in the angle between and joined from top to bottom at its lateral portionswith said first-named walls and forming with the parts of the latter relatively back of it the urinal chamber, the remaining parts In testimony whereof I afiix my signature of said first-named Walls forming projectin the presence of Witnesses.
